Memoir: Sen. Rubio says Mormon upbringing was moral compass

Florida Sen. Marco Rubio credits his short-lived time as a Mormon for providing a moral compass in his youth, though he also discloses for the first time his family’s struggles with the constraints of the faith and his eventual return to the Catholic fold.

In his new autobiography, "An American Son," available Tuesday, the Florida Republican candidly discusses the three years he spent as a member of The Church of Jesus Christ of Latter-day Saints and lauds the Utah-based faith for helping his Cuban-immigrant mother and him when they moved from Miami to Las Vegas when he was a grade-schooler.
